DUMPING-MACHINE.

Patented dan., f5, 1943..

Application led 'May 19, 1916. Serial No. 98,678.

To all whom t may concern:

Be it known that I, ALEXANDER BRADY, a citizen of the United States, and a resident of Newton Lower Falls, in the county of Middlesex and Commonwealth of Massachusetts, have invented an lmprovement in Dumping-Machines, of which the following description, in connection with the accompanying drawings, is a speciication, like characters on the drawings representing like parts.

rfhis invention relates to machines for dumping candy wafers and other articles, and is an improvement upon the machine shown in my copending application Serial No. 739,698, filed January 2, 1913. p

In the course of the manufacture of the candy wafers they are placed upon boards or shallow trays todry and then discharged from the trays in readiness to be wrapped. The present machineenables an assembly of trays to be manipulated as a unit simul-V taneously to discharge the wafers therefrom,

wafers to a minimum.

'lhe character of the invention may be best understood by reference to the followu ing description of an embodiment thereof shown in the accompanying drawings, wherein Figure 1 is a side elevation of the dumpu ing machine shown herein as embodying the invention;

F ig. 2 is a rear elevation of the machine;

Fig. 3 is a vertical section through the carrier vshowing the same in upright position;

Fig. 4 is a vertical section through the carrier and its counterbalancing means showing parts in discharging position; and

Fig. 5, on an enlarged scale, is a horizontal section through a portion of the carrier.

Referring to the drawings, the machine shown therein as embodying the invention comprises a frame having uprights 1 on which is journaled a horizontal shaft 3 pro jecting through and serving as a fulcrum for a box-like carrier 5 comprising a bottom 7, a top 9 and side walls 1l. The front end of the carrier is open and adapted to receive a truck 13 loaded with an assembly of superposed trays 15 containing the wafers. rlhe carrier may be formed to conform to the assembly of trays and thereby contribute to the holding thereof in proper assembled relation. The frame may be mounted on a door 17 having a recess 19 therein to receive the bottom of the carrier with the upper surface thereof flush with the floor to facilim tate the rolling of the truck into and out of the carrier.

To normally hold the carrier in its upright position it is provided with a spring latch 21 adapted to engage a block 23 on the floor. To release the latch a lever 25 (E ig. 2) is pivoted on said block and is urged against a stop 27 by a spring 29. rf'his lever is extended beyond the frame to present a treadle 31 which when depressed will release the latch as desired.

To manipulate or tilt the frame and the assembly of trays therein as a unit, to slide the wafers along the trays, ropes 33 or other flexible members may be connected to the carrier at points 34, and extend up over pulleys 35 and thence downward to drums 37 fast on the shaft 3 referred to, which has a crank 39 fast thereon.

When the crank is rotated it will wind the ropes on the drums and thereby tilt the carrier in a contra-clockwise direction from its position shown in Fig. 3 until the points 34 of connection of the cable with the carrier are directly above the axes of the drums. The momentum of the movement of the carrier will cause said points to swing beyond this position and then the handle is rotated gradually, slightly in the opposite direction to allow thecarrier to swing somewhat farther in a contra-clockwise direction to its position shown in F ig. 4.

To counterbalance the carrier and facilitate the tilting thereof, a rope or other flexible member 41 may be connected to the top of the carrier and pass over a fixed pulley 43 to a weight 45 adapted to slide in a well 47.

The weight is designed to counterbalance the carrier when loaded with a truck and trays and consequently will outbalance the carrier when empty. Therefore if the latch 21 is inadvertently released the weight is liable to tilt the carrier with a sharp, quick movement and injure any operative within range thereof. To prevent any possibility of this, the weight is locked at the top of the well excepting when the handle is operated to tilt the carrier. To this end a latch 49 is pivoted to the well 47 and provided with a toe 51 adapted to project through a lll@ hole 53 inl the wallA of the well beneath the weight. The latch is connected to a rope 55 or other flexible member extending up over-a pulley 5r on the frame and thence down to-a short arm 59 fast on the end of the horizontal shaft 3 opposite the handle.

Thus on the initial rotation of the handle the rope 55 will be pulled downward and rockl the latch outward and release the weight and render the same effective to counterbalance the carrier. The continued rotation of the shaft to complete the tilting ofthe carrier will Vwind the rope 55 thereon Vand rock the latch on outward to its position shown in Fig. el. When the handle is L- turned to return the carrier to its upright fcontents of the trays and permit the sameV anchored to thecross'member 67. Movement of the lever by the spring is limited by a position the latch will gradually rock downward, and after the weight reaches the upperfend ofthe well, will project beneath thesame as shown in Fig. l.

In the machine shown in my said copending application, the carrier is provided with a fixed' wall located a considerable distance from thedelivery ends of the trays to form a chamber sufficiently largeto receive the tofslide along thewall and discharge from the `carrier. In dropping through this consideraiblefspace between the trays and the fiXedll wall many of the wafers were liable to be broken.

An important feature of the invention relates to'means for preventing this breakage. To accomplish this the carrier is provided witha wall 61 adapted to receive the wafers from thetrays and move gradually away therefrom to'allow the wafers to slide along saidfiwall' land discharge from thel carrier.V

To shift the Wall toward-and from the trays, leaves 63 may be provided extending the .length of the carrier and hinged to upper andilower cross members 65 and an inter'- mediate cross member 67 on the frame. These leaves are folded back against said members to permit the wall to move awayA from` said trays'and arefolded into posi tions perpendicular to said members to shift the wall back toward the trays. To control the flea-ves in this manner they are provided with ar'iiis 69 fastthei'eon, connected by links' 47l with a lever 73 fulcrumed intermediate its ends on the member 67. To shift the lever to move the wall tewardthe trays, a"

spring is` provided having one end connected to said lever and its opposite end stop 77 on said cross member.

To Shift the lever to permit the wall to moveaway from said trays, a rope 79 or vother flexible member may have one end connectedyto said lever and extend thence through a guide eye 81 on the carrier and have-its opposite end anchored to an eye S3 on the frame.` This rope has suficient slack V.so that it will beineifeetive to shi-ft the lever untilthe carrier approaches the limit of its tilting movement to discharge. On the occurrence of this event the rope 79 lwill YbeV tightened to shift the lever73`in 'a clockwise direction (Fig. Q), thereby gradually'ioclrings-aid leaves from their full line positions shown in; Fig. 5 to their dotted linev positions Y The weight of the" saidwall. ATo yautomatically'operate the gate itis connectedfto a'frop'e 875er other suitable flexibleconnection which is guided over a pulley 89-mounted on the carrier'and connected to a weight 91 adapted to slide iira'pocketlQS'of the'carrier.

lV heir the carrier is in vits upright position the weight will gravitate tothe bottom of its pocket and hold the gate Vclosedas `shown in Fig. l. Butwhen the'carrier is tilted toits discharging position-'the weightwill slide tot-heopposite end of its pocket1 and allow the gate to open and'permit thevwafers to slide along the wall therefrom.`

Preferablythe Wall should be spaced some-` what from the edges of the l traysA to furnish a chambergoffsufli'cient"size toV accommodate' the wafers as theyslide from the trays on the tilting ofthe carrier and before the l movement ofthe wallfawaylfrom the trays.v

To provide such a chambena frame 9,5V may be'introduced in'tofthe carrier andserve 'as an abutment to receivethe inner ends of the ,l

trays andhold them spaced from therear end of theca'rrier.- vv'llliuswhen the carrier y tilted todischarging position", 'the wafers, will slide into this chamber against the'wall Gl, but the chamber is'so shallow that the wafers will not dropl 'al sufficient' distance to break them 't l To check the sliding' of the wafers along said wall before it is moved awayy fromV the edges ofthetrays, a seriesof partitions $7 i maybeintroducedinto said chamber and hinged to' saidfframe. They are freete swing in one direction, butare limited by stopsQQvon the frame'fromswinging inthe opposite direction; "As a resultthe partitions will be properlylield to checkl the sliding of the wafers aloiig'the wall during the first part o-flthetilting .of the' carrier, butV will be freeto swing to their positioiisshown in Fig. lto facilitate the discharge 'of the wafers during the latter partof the tilting of the carrier and when the wall is' being moved gradually away from the edges ofl thetrays..
